I can see using a spray lube on a very very dry neglected sewing machine that will be cleaned thoroughly and properly lubed after it's freed up. But to hose a machine with a spray lube because you're in a hurry just makes a mess. Plus the excess just builds up everywhere and makes a machine that much harder to maintain down the road.
I've cleaned so many that have been amber with old oil and lube that I just can't do that.

And those that have been hosed with WD-40 are usually a disaster down the road. That stuff is not a lubricant per sea, but a water dispersant with some limited and temporary lubricating ingredients.

It takes so little time to properly oil a normal machine ( I agree with you about the current plastic wannabee machines ) that I just have to disagree ( politely of course ) with using an aerosol lube for a quicky lube.

On old sewing machines and many not so old, there is a rule of thumb .... if the hole isn't threaded - it's an oil hole. Oil it.
